TO ALL WHOM IT MAY CONGERN:

Be it known that I, HENRY C. SERGEANT, of Columbus, in the county of Franklin, in the State of hioi. have invented a new and improved Mode of Constructing Brick Machines; andV I do hereby declare that the following is a full and exact description thereof, reference being had to -the accompanying drawings, and to the letters of reference marked thereon.

j The nature of my improvement consists in the arrangement of the trackfor `supporting and raising and:v lowering the followers; also the mode of constructing and operating the striker-plate, and a new mode of" pressing the bricks after they have passed out frotn under the pug-mill.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation. i i

Figure l represcnts'the frame of the machine A A A A, mould-wheel D, bottom of the pug-mill C C, and brick-press D.-

Figure 2 shows a section of the brick-press and mould-wheel and track, also the follower, and position of the brick whilst under pressure.

Figure `3 represents the track for raising and lowering the follower.

Figure il represents the bottomot` the pug-mill and set-'screws a a for adjusting the knife upon the face of the mould-wheel fb shows the slot in lug attached to the pug-mill bottom, through which passes the bolt c, shown in lig. 5, which is the striker-plate and knife. i

v I use the ordinary mixers and tub for filling the moulds whilst under the pug-mill, consequently I have none represented. By them-rangement of the-track shown in'g. 3, figs. 1, 2, 3, 4, 5, and 6 show the different points of' the inclinesin the trac-k, which is arranged so that the follower is lowered about an inch before it passes underneath the pug-mill, andy then is lowered whilst underneath the pug-mill for the purpose of allowing the e'lay'to be pressed into the lower portion of the mould first, and passing downwhile still underneath the pug-mill so as to receive the required amount of clayfor thel brick. It being adiicult matter, without producing a. great deal of friction, to press the clay into the brick-mould and fill the corners perfect when the clay is still` and the mould two and a halt' or three inches deep, t-hereare many devices for making adjustable striker-plates, James Hotchkisss wooden pins, Sie., which are arranged so as to break when the knife attached to the strikerplate comes in contact with stones or any other unyieiding matter.

Letter d, shown in iig. 4, represents a slot cast in the projecting lug from the bottom of the pug-mill. The striker-plate is placed in a recess for it on the under side of the lug, the bolt c in the striker-plate fitting into slot and held toits place by the bolt. The knife is' adjusted by means of two set-screws a a. By this arrangementl dispense with the outside scraper entirely; As the mould-wheel revolves the bricks pass out from under 'the striker-plate and around to the pressi), represented in fig. 2. This press has an arm with one end hinged upon the shaft, 'as shown in 1, and a roller on the othervend, as shown in fig. 2. On the outside of the mould-wheel are placed square pins or projections, to correspond with each mould in the wheel,whieh may be ten or twelve in number. When one of these pins comes in contact with the projection on the end of the arml shown at e, fig. 2, it carries the arm D around with the mlould-wheeL-and at the same time that the arm begins to rise on the incline in the track, shown in iig. 3 at 4, presses the brick up against the arm D, as shown in iig. 2. This is held down to the face of the mould-wheel while the brick is being pressed by the roller passing under the pivoted bearing shown at letter-f. After the r'oler of the follower has passed the point or rise on the track for pressing the brick, the lower end of' the projection on the end of the arm D comes in contact with the incline, shown in fig. 1 by letter g, whichraises the arm `D from'the face of the mould-wheel, (the roller having passed out from its bearingabove,) and relieves the project-ion e from the pin on the rim of the mould-wheel, and at the saine time shoves back the pivoted armf, and allows the arin D to return to its former position,`alsothe pivotcd arm f, both being returned to their former positions, (by means of springs or weights,) ready to repeat the operation when the next mould reaches the press. The bricks are raised to the' surface of the mould-wheel by means of an additional risc in the track, shown at 5 and 6 in iig. 3.

Having thus fully described my improvement, 'I will state what I claim as new, and desire to secure by Letters Patent;

1. I claim lowering the followers at intervals, or continuing the lowering while under the pug-mill, (as the moulds are being lled,) to facilitate theflling of the corners of the moulds.

2. I claim the adjustable striker-plate having a. bolt and slot foi' clampinas shwn and described. 3. I claim the arm D, having an intermittent motion in combination with the rise vin the track, as shown and described.

4. I claim the pins or projeceionson the rim of the muld-wheel, for giving motion to a. pressure-plate or. arm D, or its equivalent, as shown and described. A
